measured in volt-amps (VA). Apparent power is a product of the effective voltage multiplied by the effective current. Apparent power is calculated by the formula: Only when the AC circuit is made up of pure resistance is the apparent ... power equal to the true power. [Figure 12-141] When there is capacitance or inductance in the circuit, the current and voltage are not exactly in phase, and the true power is less than the apparent power. The true power…

Electrical Temperature Measuring Indication The use of electricity in measuring temperature is very common in aviation. The following measuring and indication systems can be found on many types of aircraft. Certain temperature ranges are more suitably measured ... system. Figure 10-67. A bimetallic outside air temperature gauge and its installation on a light aircraft. Electrical Resistance Thermometer The principle parts of the electrical resistance thermometer are the indicating instrument, the temperature-sensitive element (or bulb…

total current flow into the node A equals the sum of the branch currents, which is: IT = I1 + I2 Substitute IT = 5 mA + 12 mA IT = 17 mA The total current entering node B is also the same. Figure ... illustrates how to determine an unknown current in one branch. Note that the total current into a junction of the three branches is known. Two of the branch currents are known. By rearranging the general formula, the current in branch…
